Side-story DLC Severed is half-price during this time, as is the game's extra weapons and suits packs.

The other nine titles in the offer include Darksiders and Renegade Ops, which will be replaced on 15th August. Outland, Oddworld: Stranger's Wrath HD, Lara Croft and the Guardian of Light, Saints Row 2, inFamous 2, MotorStorm Apocalypse and LittleBigPlanet 2 complete the roster.

As a bonus, newly-released (on PS3) tower defense-meets-pinball mashup Rock of Ages is also free. That offer lasts until 29th August.
